LETTERS TO THE EDITOR
This technique is a simple, safe, and dependable means of producing underwater seal drainage for patients of any age with spontaneous pneumothorax. Al1 the equipment needed is readily available in the operating room. Therefore, a workable underwater seal apparatus can be functioning within minutes in the event of a life-threatening pneumothorax.

Syndrome
To the Editor:
In a recent case report, “Cardiovascular Collapse and Refractory Bronchospasm Following Administration of Vancomycin, Esmolol, and Heparin,” Bloom et al state in the Discussion that “Vancomycin is an aminoglycoside antibiotic; thus, it shares the potential toxicity that this group possesses as a whole.“’ In fact, vancomycin is not an aminoglycoside antibiotic, but is a glycopolypeptide that is unrelated to al1 other antibiotics.*.3 Moreover, the quoted side effects of “fever, nausea, pain on injection with or without phlebitis . . .” are relatively rare adverse effects of the aminoglycoside antibiotics.4 Nephrotoxicity, although a complication encountered with both classes of antibiotics, is now infrequent with the newer, more pure preparations of vancomycin.3.5 Finally, one wonders whether the rarity with which the “red-man syndrome” has been reported in the cardiac anesthesia literature is related to the not uncommon practice of giving both H,- and H,-blockers prior to the induction of anesthesia and the administration of vancomycin. As correctly noted by the authors, pretreatment with histamine antagonists may prevent the occurrence of this syndrome. Christopher O’Connor, MD
